How to remember the ATM Card's PIN? No you don't.Thats the simple answer.You need to write it down!
Write?But don't all those card companies tell us "Never Write the PIN anywhere"? Thats if all you have is one card and you have no trouble remembering it.Anything more, its near impossible to remember the PIN's for all the cards- especially if you use the cards rarely.
What we can do is write it in a safe place (Which of course means not in a slip in the card pouch!!).
